This embodiment provides a charging adapter device, as shown in FIG. 1 to FIG. 3 , the charging adapter device 1 includes a connector 1, an adapter plate 4 and two pins 2. The connector 1 includes a housing 11 and a terminal 12, and the adapter plate 4 is arranged in the housing 11 and electrically connected to the terminal 12. The two pins 2 are separately electrically connected to the adapter plate 4 so as to be electrically conductive with the connector 1 through the adapter plate 4. In the present application, the number of pins 2 is given as an example, and the number of pins 2 can be adjusted as needed, for example, 4 pins or more.

In this embodiment, the connector 1 is connected to the two pins 2 through the adapter plate 4. When the two pins 2 are connected to a product, the product can be charged through the connector 1, so that the connector can be used in common with chargers of other electronic products to achieve the convenience of product charging. Moreover, the charging adapter device in this embodiment is adopted, so that the product has a relatively small change in structure, the charging adapter device has a small volume, and it is convenient to carry the charging adapter device.

For example, for electronic products having batteries, an internal battery module of the electronic product typically has a two-pin input end, and the two-pin input end can be used to be connected with an external power supply so as to receive power to charge a battery. However, an output end of the external power supply has many kinds of specifications. Therefore, the electronic product needs to be provided with a charging adapter module with a specific specification corresponding to an output end of an external power supply with a specific specification, so that the output end of the external power supply is electrically connected to the internal two-pin input end through the charging adapter module. Due to the charging adapter module with the specific specification, the internal structure of the electronic product may need to be specially designed for adaptability, which leads to a relatively great change in the structure of electronic product. In this embodiment, the versatility of the charging adapter device can be improved. In some embodiments, the connector 1 is a USB interface, and the connector 1 can be docked with an output end of an external power supply conforming to the USB specification. Since the external power supply conforming to the USB specification is relatively common, the connector 1 of the charging adapter device can be conveniently connected to various external power supplies conforming to the USB specification. In addition, through the adapter plate 4 and the pins 2 of the charging adapter device, the electric power received by the connector 1 can be conveniently input into a battery module through the adapter plate 4 and the pins 2, and the charging adapter device can be simply arranged in a housing of the electronic product and extend to the interior of the electronic product.

In order to further improve the convenience of using the charging adapter device, in some embodiments, the connector 1 is a type-C interface conforming to a USB type-C specification. The type-C interface has a thinner thickness, so that a volume of the charging adapter device can be reduced. Of course, those skilled in the art can set the form of the connector 1 as required, and the form of the connector 1 is not limited herein.

In some embodiments, the adapter plate 4 includes a flexible printed circuit (FPC) by which the electrical connection between the connector 1 and the pins 2 is achieved. In this embodiment, the adapter plate 4 includes a printed circuit board (PCB) through which the connection between the connector 1 and the pins 2 can be facilitated. Of course, those skilled in the art can set the form of the adapter plate 4 as required, and the form of the adapter plate 4 is not limited herein.

In order to further improve the convenience of connection between the pins 2 and the adapter plate 4, as shown in FIG. 3 , the pins 2 are perpendicularly inserted into the adapter plate 4. In some embodiments, the adapter plate 4 is provided with first sockets matched with the two pins 2, respectively, and each pin 2 is inserted into one first socket. In some embodiments, the pins 2 are welded in the first sockets, respectively, so that the pins 2 are reliably connected to the adapter plate 4.

In some embodiments, as shown in FIG. 3 , terminals 12 of the connector 1 are perpendicularly inserted in the adapter plate 4, thereby facilitating the connection between the terminal 12 of the connector 1 and the adapter plate 4. In some embodiments, the adapter plate 4 is provided with second sockets which match the terminals 12 on the connector 1 in one-to-one correspondence, and each terminal 12 of the connector 1 is inserted into a respective one of the second sockets. In this way, the connector 1 is reliably connected to the adapter plate 4, and the assembly efficiency can be improved. In the present application, the number of pins 2 is different from the number of terminals 12, and the adapter plate 4 electrically converts the terminals 12 of the connector 1 into the pins 2. In some embodiments, as shown in FIG. 3 , FIG. 6 and FIG. 8 , the number of terminals 12 is 8 as an example, and the eight terminals 12 can be converted into the two pins 2 by the adapter plate 4. In practice the number of terminals 12 can be adjusted as needed. In some embodiments, the number of terminals 12 is greater than the number of pins 2.

In some embodiments, the adapter plate 4 is perpendicularly disposed between the pins 2 and the terminals 12 of the connector 1. The term “perpendicularly” described herein refers to that an extension direction of the pins 2 and an extension direction of the terminals 12 of the connector 1 are perpendicular to two opposite main surfaces of the adapter plate 4. The two pins 2 are perpendicularly inserted onto one of the two main surfaces of the adapter plate 4 and fixed on the one of the two main surfaces of the adapter plate 4. The terminals 12 are perpendicularly inserted onto another of the two main surfaces of the adapter plate 4 and fixed on the another of the two main surfaces of the adapter plate 4. In this way, the adapter plate 4 is tightly sandwiched between the two pins 2 and the connector 1, so that the whole charging adapter device is more compact, thereby reducing the space occupied in the electronic product.

In some embodiments, the connector 1 further includes a body 13 and a tongue plate 14 extending from the body 13 in a direction facing away from the adapter plate 4. The body 13 is located between the tongue plate 14 and the adapter plate 4. One end of the terminal 12 extends to the tongue plate 14 in the extension direction of the terminal 12 and another end of the terminal 12 extends to the adapter plate 4 in the extension direction of the terminal 12.

The housing 11 and the body 13 define a first accommodation space 61, and the tongue plate 14 is located in the first accommodation space 61. In some embodiments, as shown in FIG. 3 , the connector 1 further includes contacts 17 disposed on two opposite sides of the tongue plate 14. In some embodiments, the number of the contacts 17 is different from the number of terminals 12. In some embodiments, the number of the contacts 17 is greater than the number of terminals 12. In some embodiments, the number of the contacts 17 is greater than the number of the pins 2. It is to be noted that not all of the contacts 17 extend through the body 13 to form the terminals 12, but only a part of the contacts 17 extend through the body 13 to form the terminals 12. In some embodiments, as shown in FIG. 3 , the connector 1 is a type-C interface, and thus the number of the contacts 17 is 24. In some embodiment, the number of the contacts 17 is greater than the number of the terminals 12, and the number of the terminals 12 is greater than the number of the pins 2.
